Caveat

The example is for illustrative purposes. It shows an example with content and embedded semantic correspondence statements. However, the example does not show you how to build a data catalogue or XML schema definition for any particular service. In particular, the design options e.g. using elements/complex types should not be taken as definitive.

Service description example

The Donlon TOBT Setting Service Description describes a service that supports the Airport Collaborative Decision Making (A-CDM) concept and its implementation by allowing A-CDM partners, typically aircraft operators and ground handlers, the capability to set the Target Off-Block Time (TOBT) that indicates the target time for the aircraft to be ready for Off-Block.

It contains an example information definition as it could appear in a service description. The example covers the messages that are part of the service: TOBTSettingRequest, TOBTSettingResponse, TOBTDeleteRequest and TOBTDeleteResponse.

The data catalogue and XML schema example below are aligned with this information definition. Examples of two of these messages in XML format are included to promote an easier understanding of the schema.

Data catalogue example

The same content can be represented in a tabular data catalogue format. The following figures show how this could look. It is possible to download the completed spreadsheet: donlon_data_catalogue.xlsx

The spreadsheet contains identification, responsible party and scope information in one tab.

This tab also contains links to the four messages contained in the information definition. Each of these tabs includes the concepts and their semantic correspondence. This is illustrated for the TOBTSettingRequest below.
